Diana Cruise is a 6-star luxury vessel launched in 2025, sailing the quieter waters of Lan Ha Bay — the less-crowded, more pristine side of the UNESCO World Heritage site, where dramatic limestone karsts rise from emerald waters without the tourist crowds of the main bay.
56 cabins across six categories. Diana Junior and Senior cabins (34m²) feature private balconies and en-suite bathtubs. Executive and Premier cabins (36–38m²) add extra space and upgraded furnishings. The flagship Diana Halong Suite and Diana Lan Ha Suite (55m²) each feature oversized private terraces — ideal for sunrise over the karsts. All cabins include high-speed Wi-Fi, 24/7 satellite TV, and premium in-room amenities.
Rated 5.0 from 2,500+ verified guests — consistently praised for spacious cabins, attentive crew, and the calm scenic route through Lan Ha Bay.
Couples, honeymooners, and travellers who want genuine 6-star comfort with a quieter bay experience. Fewer boats, cleaner water, and a more personal atmosphere than the main Halong Bay corridor.
